A wide (80 nm) double-barrier resonant tunneling structure shows 25 features in the current-voltage characteristic associated with resonances in the quantum well. When a transverse magnetic field is applied to the structure, the features weaken and shift to higher energies. We give a quantum mechanical description of this phenomenon which is able to account quantitatively for the magnitude of the shifts.
